The E92/E90 M3’s V8 deserves to be heard. Our valved stainless steel catback unlocks its true character—delivering sharper volume, deeper tone, and the raw aggression the S65 engine was built for. Open the valves and unleash the full exotic V8 symphony: crisp, high-revving, and unapologetically loud. Close them and it dials back, perfect for calm commutes or early morning starts. Crafted from T304 stainless, precision TIG welded, and 3D scanned for an OEM+ fit. Loud when you want it. Civil when you need it. Built for daily-driven chaos.
Features:
- Louder, more aggressive sound–with zero drone
- X-pipe design amplifies the M3’s exotic V8 sound
- Valve-controlled chaos: violent when open, stealthy when shut
- Built from 100% T304 stainless steel with pro-grade TIG welds
- Engineered using 3D scans for perfect fitment and a clean, OEM+ fit
- Direct bolt-on installation with complete hardware mounting kit
- Lighter than stock for a slight edge in performance
- Comes standard with a free HOA violation
